First Sale Valuation: How Importers Can Legally Lower Customs Value

What is first sale valuation?

First sale valuation is a customs valuation method that allows importers in a multi-tier supply chain to base customs duties on the price of an earlier transaction (typically the sale from manufacturer to middleman) rather than the final sale price to the U.S. importer. Because the earlier transaction price is typically lower, importers pay duties on a reduced customs value, resulting in legitimate duty savings.

Is first sale valuation legal?

Yes. First sale has been an accepted valuation methodology in the United States for decades, established in the Federal Circuit's ruling in Nissho Iwai American Corp. v. United States and codified in CBP Treasury Decision 96-87. However, bipartisan legislation introduced in February 2026 (the Last Sale Valuation Act) would eliminate first sale if enacted, making this a strategy importers should implement carefully and monitor closely.

With U.S. tariff rates at their highest since 1943, importers are looking for every legitimate method to reduce duty costs. First sale valuation is one of the most powerful tools available, with potential savings of 20% or more on duty payments. A hypothetical importer of $5 million in goods at a 15% duty rate would pay $750,000 annually in duties. Implementing a first sale program with a 20% reduction in customs value could save approximately $150,000 per year. Over a decade, that compounds to over $1.5 million in savings. But the strategy carries significant compliance risk if poorly implemented, and its long-term viability is now under legislative threat.

How Does First Sale Valuation Work?

In a standard import transaction, customs duties are based on "transaction value," which is the price paid or payable to the seller. When the supply chain involves only two parties (foreign seller and U.S. buyer), there is only one transaction price to use.

But many supply chains involve multiple tiers: a foreign manufacturer sells to a foreign distributor or trading company, which then sells to the U.S. importer at a markup. Under normal valuation, duties would be based on the higher price the U.S. importer pays (the "last sale"). Under first sale valuation, the importer can declare the lower price from the manufacturer-to-middleman transaction as the customs value.

Standard valuation: Manufacturer ($8/unit) sells to Distributor, who sells to U.S. Importer ($10/unit). Duty calculated on $10.

First sale valuation: Same supply chain, but duty calculated on $8/unit instead of $10/unit, a 20% reduction in dutiable value.

What Are the Requirements for Using First Sale?

CBP requires importers to satisfy several conditions before using first sale, all rooted in demonstrating that the earlier transaction is a bona fide arm's-length sale destined for the United States.

Two bona fide sales. Both the manufacturer-to-middleman sale and the middleman-to-importer sale must be legitimate, commercially reasonable transactions. CBP examines purchase orders, invoices, proof of payment, and other documentation from both tiers.

Clear export intent. At the time of the first sale, there must be a clear intent that the goods would be exported to the United States. Evidence includes shipping instructions, U.S.-specific markings or labeling, contracts referencing U.S. delivery, and order documentation specifying U.S. destinations.

Title and risk transfer. The middleman must acquire title to the goods and assume risk of loss during the transaction. If the middleman never truly owns the goods, CBP will not recognize the first sale as a legitimate transaction.

Arm's-length pricing. Whether the parties are related or unrelated, the pricing must reflect commercially reasonable terms. If the manufacturer-to-middleman price appears artificially low, CBP may challenge the first sale claim.

Comprehensive documentation. Importers must maintain records supporting every element of the first sale: invoices from both tiers, proof of payment at each level, evidence of title transfer, shipping documentation showing U.S. destination intent, and contracts between all parties.

What Are the Risks of First Sale Valuation?

CBP actively scrutinizes first sale claims, and in 2026, CBP is sending out First Sale Valuation Questionnaires to importers using the methodology. Consequences of errors include retroactive duty assessment (with interest) for up to five years, penalties ranging from two to four times unpaid duties for negligence, and potential referral to the DOJ Trade Fraud Task Force for intentional misrepresentation.

Common failure points include discrepancies between freight/insurance documentation and declared values, middlemen who do not truly take title or assume risk, pricing that does not reflect commercial reality, and insufficient documentation of U.S. export intent at the time of the first sale.

Is First Sale Valuation Under Legislative Threat?

Yes. On February 11, 2026, Senators Bill Cassidy (R-LA) and Sheldon Whitehouse (D-RI) introduced the Last Sale Valuation Act, bipartisan legislation that would require duties to be calculated based on the "last sale" before exportation to the United States, effectively eliminating first sale valuation.

The bill has been referred to the Senate Finance Committee. While it faces significant industry opposition and would need to pass both chambers, the bipartisan sponsorship and the current administration's focus on maximizing tariff revenue suggest importers should prepare for the possibility.

As Greenberg Traurig has noted, the elimination of first sale would be "challenging to the myriad of importers, manufacturers, wholesalers, and retailers currently using the duty mitigation strategy."

FAQ

How much can first sale valuation save on duties?

Savings depend on the markup between the first sale price and the last sale price. Typical savings range from 10% to 30% of duties paid, though the actual amount varies by product, supply chain structure, and applicable duty rates. At current tariff levels, even modest percentage reductions can translate to significant dollar savings.

Can related parties use first sale valuation?

Yes, but CBP applies additional scrutiny to related-party transactions to ensure the first sale price reflects arm's-length commercial terms. Importers must demonstrate that the relationship did not influence the price paid. Transfer pricing documentation may be relevant.

What happens if the Last Sale Valuation Act passes?

If enacted, importers would be required to declare customs value based on the final transaction price before exportation. Companies currently using first sale would see immediate duty increases. Importers should assess the potential financial impact and consider alternative duty mitigation strategies (FTZs, duty drawback, sourcing optimization) as contingencies.

How do I implement a first sale program?

Implementation requires a thorough analysis of your supply chain, identification of qualifying multi-tier transactions, collection and organization of supporting documentation, and often a binding ruling request to CBP for legal certainty. Working with experienced trade counsel is strongly recommended given the compliance risks.
